(August, 2010) This appendix gives an overview of the basic maps and sections to be delivered together with the report for a SkyTEM survey. All maps must be in Euref zone 32 (33) UTM coordinate system. Information about gridding method, search criteria for geological layers etc. is given in the report or in the map legends. Kriging is normally the preferred gridding method. Refer to 1 for general information about presentation of TEM-inversion results. The basic maps are divided into three groups: Survey location, data, and inversion results. Specifications for the different theme maps are listed in the tables. All theme maps are composed with basic background maps e.g. KMS-map, air photos. The tables below distinguish between digital maps (D) and printed maps on paper (A). Digital maps are delivered in the Aarhus Workbench survey workspace. Printed maps are printed on paper appearing in the report. They are also delivered in pdf format and present in the Aarhus Workbench Workspace. The themes can be either by color coded points (P) or gridded bitmaps images (G). For some surveys it can be optimal to produce other/more theme maps. Theme Digital/Paper Point/Grid Planned survey area and planned flight lines. Planned survey area, actual flight lines with overlay of coupling sources (roads, power lines etc.), landing location and local test site. D A Theme Digital/ Paper Point/Grid Flight altitude A P Flight speed D P Raw data positions overlaid by model positions (non-coupled data). This map shows where data have been excluded during the processing. Presence of moments – with a two-moment system, the color code is: Both SLM and HM (green), SLM only (red) , HM only (blue). Number of gates for each moment. One map per moment. D P A A P P The maps are created for each inversion (one set of maps for smooth inversion, one set for the few-layer inversion).

(August, 2010) !" The following maps are delivered for few-layer models. Note: Resistivity maps must be gridded on the logarithm to the resistivity. Themes Digital/ Paper Point/Grid Horizontal mean resistivity maps in 10 m elevation intervals. D G Horizontal mean resistivity maps in depth intervals. 5 m intervals down to 20 m. 10 m intervals from 20 m to 50 m. Elevation of the conductive subsurface (if present). The conductivity of the layer must be determined from histograms of the resistivity distribution in the deeper layers.

A G A G Sections are typically created along flight lines. A number of sections illustrating central geological elements are selected. Typically, 10-20 sections are printed, and additional sections are present in the Workspace. The sections contain: resistivity models, boreholes, and DOI. There is a set for both smooth and layered models. Same scale and orientation are used for all sections. Themes Digital/ Paper Point/Grid Location of profiles inc. model and boreholes positions.
